Australia 2019

The Australian 2019 general election is 18 May. In fact, as I enter this text, it is only about an hour and half before polls open in the eastern part of the country (thus about 14.5 hours before they close in the west), even though it’s midday Friday where I am. So, for now I will leave the task of discussing election day and the early results to my several capable Australian commentators, as well as anyone else who wants to chime in.

I recommend this background piece in Inside Story on the history of Australian election results. Also this piece by Antony Green on calculating swings.

Indonesia 2019

Indonesia’s general elections are on 17 April. For the first time, these will be concurrent–president and assembly on the same date. Previously, since the country’s 1990s democratization, assembly elections had been held in the counterhoneymoon, i.e., several months before the presidential election.

Indonesia has a wonderful election mascot. We need more of these in the world of elections.

New Zealand to have referendum questions on 2020 ballot, potentially including “tweaks” to MMP

Earlier in December, the Justice Minister of New Zealand, Andrew Little (Labour) announced that there would be a binding referendum on recreational cannabis use concurrent with the 2020 general election. There may also be a question on euthanasia, and–of core interest to this blog–electoral reform.

Earlier, Little had said:

It has been floating around that if we’re going to do a bunch of referenda, why wouldn’t we put this question about whether we want to make those final tweaks to MMP, reduce that 5 per cent threshold to 4 per cent, get rid of the one-seat coat-tailing provision.

These proposals were part of the Electoral Commission’s MMP Review, but the government at the time (National-led) did not act on them.

The multiparty nature of the New Zealand political system that MMP has institutionalized is apparent in these issues being on the table. Having a referendum on cannabis use was a provision of the confidence and supply agreement that Labour signed with the Green Party after the 2017 election. In addition, Labour’s other current governing partner, New Zealand First, has indicated support for a bill on euthanasia sponsored by the leader of ACT, another of the smaller parties (a right-wing partner to opposition National).

Both provisions that the MMP Review recommended changing have had past impacts on current parties. The ACT has depended for its representation in parliament on the so-called coat-tailing provision (a term I do not like for the alternative threshold) in several elections. The New Zealand First once was left out of parliament for having a vote share between 3.5% and 5%, despite other parties (including ACT) being represented, due to winning a single district (electorate) plurality. (Obviously, 4% would not have helped NZF in 2008, as it had only 3.65%. But the point is that the current provisions produce potential anomalies; I have suggested before that the two thresholds should be brought closer to one another.)

Also of note: Little said that the cabinet had discussed, but decided against, having a citizen’s assembly to deliberate issues related to cannabis (and perhaps also euthanasia).

Is AV just FPTP on steroids?

In debates over electoral systems in Canada, one often hears, from otherwise pro-reform people, that a shift to the alternative vote would be worse than the status quo. It is easy to understand why this view might be held. The alternative vote (AV), also known as instant runoff (IRV), keeps the single-seat districts of a system like Canada’s current first-past-the-post (FPTP) system, but replaces the plurality election rule in each district with a ranked-ballot and a counting procedure aimed at producing a majority winner. (Plurality winners are still possible if, unlike in Australia, ranking all candidates is not mandatory. The point is that pluralities of first or sole-preference votes are not sufficient.)

Of course, the claim that AV would be FPTP on steroids implies that, were Canada to switch to AV, the current tendency towards inflated majorities for a party favored by less than half the voters would be even more intensified. This is plausible, inasmuch as AV should favor a center-positioned party. A noteworthy feature of the Canadian party system is the dominance, most of the time, by a centrist party. This is unusual in comparison with most other FPTP systems, notably the UK (I highly recommend Richard Johnston’s fascinating book on the topic). The party in question, the Liberal Party, would pick up many second preferences, mainly from the leftist New Democratic Party (NDP) and so, according to the “steroids” thesis, it would thus win many more seats than it does now. It might even become a “permanent majority”, able to win a parliamentary majority even if it is second in (first-preference) votes to the Conservatives (who thus win the majority or at least plurality of seats under FPTP). The “steroids” claim further implies that the NDP would win many fewer seats, and thus Canada would end up with more of a two-party system rather than the multiparty system it has under FPTP.

There is a strong plausibility to this claim. We can look to the UK, where AV was considered in a referendum. Simulations at the time showed that the Liberal Democrats would stand to benefit rather nicely from a change to AV. While the LibDems are a third party, heavily punished by the FPTP electoral system even when they have had 20% or so of the votes, what they have in common with the Canadian Liberals is their centrist placement. Thus, perhaps we have an iron law of AV: the centrist party gains in seats, whether or not it is already one of the two largest parties. An important caveat applies here: with the LibDems having fallen in support since their coalition with the Conservatives (2010-15), the assumptions they would gain from AV probably no longer apply.

On the other hand, we have the case of the Australian House of Representatives, which is elected by AV. There, a two-party system is even stronger in national politics than in the FPTP case of the UK, and far more so than in Canada. (When I say “two party” I am counting the Coalition as a party because it mostly operates as such in parliament and its distinct component parties seldom compete against one another in districts.)

It is not as if Australia has never had a center-positioned party. The Australian Democrats, for example, reached as high as 11.3% of the first-preference votes in 1990, but managed exactly zero seats (in what was then a 148-seat chamber). Thus being centrist is insufficient to gain from AV.

Nonetheless, the combination of centrism and largeness does imply that Canada’s Liberals would be richly rewarded by a change to AV. Or at least it seems that Justin Trudeau thought so. His campaign promised 2015 would be the last election under FPTP. While he did not say what would replace it, he’s previously said he likes a “ranked ballot” and he pulled the plug on an electoral-reform process when it was veering dangerously towards proportional representation.

Still, there are reasons to be somewhat skeptical, at least of the generalization of the Australian two-party experience. The reasons for my caution against the “steroids” view are two-fold: (1) the overlooked role of assembly size; (2) the ability of parties and voters to adapt.

Assembly size is the most important predictor of the size of the largest party, disproportionality, and the effective number of seat-winning parties in countries that use single-seat districts. (It is likely relatively less important when there are two rounds of voting, as in France, but still likely the most important factor.) This is a key conclusion of Votes from Seats. It is thus important not to overlook the fact that Australia has an assembly size considerably smaller than Canada’s. In the book, Taagepera and I show that Australia’s effective number of seat-winning parties and size of largest parliamentary party are almost what we would expect from its assembly size, even if FPTP were used. (See also this earlier post and its comment thread; how close it is to expectation depends on how we count what a “party” is.) The data are calculated over the 1949-2011 period, and the effective number of parties has been just 1.10 times the expectation from the Seat Product Model (which is based only on assembly size when single-seat districts are used). Similarly, the average largest party has been 93% of the expected size (averaging 54.2% of seats when we would expect 50.5%).

Thus we do not need to invoke the alleged steroids aspect of AV to understand the dominance of two parties in Australia. But this does not mean it would not make a difference in Canada. Consider that the current effective number of parties and size of the largest party in that country, averaged over a similar period, are also just about what we should expect. The multipartism, including periodic minority governments, that characterize Canada are not surprising, when you use the Seat Product Model (SPM). They are surprising only if you think district magnitude is all that matters, and that FPTP is FPTP. But it isn’t! An electoral system using the FPTP electoral rule with an assembly of more than 300 seats is a different, and more multiparty-favoring, electoral system than one with 150 seats. Replace “FPTP” in that sentence–both occurrences–with “AV” and it is surely still true.

But what about the centrist party, the Canadian Liberals? Surely AV would work differently in this context, and the Liberals would be a much more advantaged party. Right? Maybe. If so, then it would mean that the SPM would be overridden, at least partially, in Canada, and the largest party would be bigger than expected, for the assembly size, while the effective number of parties would be lower than expected. Of course, that’s possible! The SPM is devised for “simple” systems. AV is not simple, as we define that term. Maybe the SPM is just “lucky” that the one country to have used AV for a long time has the expected party system; or it is lucky that country has the “correct” assembly size to sustain two-party dominance. (Australia is the Lucky Country, after all, so if the SPM is going to get lucky one place, it might as well be Australia.)

This is where that other factor comes in. While no one has a crystal ball, I am going to go with the next best thing. I am going to say that the SPM is reliable enough that we can predict that, were Canada to have AV, it would have an effective number of parties around 2.6 and a largest party with around 48% of seats. In other words, just about where it has been for quite some time (adjusting for the House size having been a bit smaller in the past than it is now). Note these are averages, over many elections. Any one election might deviate–in either direction. I won’t claim that a first election using AV would not be really good for the Liberals! I am doubting that would be a new equilibrium. (Similarly, back in 2016 I said my inclination would not be to predict the effective number of parties to go down under AV.)

Parties and voters have a way of adapting to rules. Yes the Liberals are centrist, and yes the Conservatives are mostly alone on the right of the spectrum (albeit not quite as much now, heading into 2019, as in recent years). But that need not be an immutable fact of Canadian politics. Under AV, the Liberals might move leftward to attract NDP second preferences, the NDP center-ward to attract Liberal and even Conservative second preferences, the Conservatives also towards the center. It would be a different game! The Greens and other parties might be more viable in some districts than is currently the case, but also potentially less viable in others where they might win a plurality, but struggle to get lower ranked preferences. The point is, it could be fluid, and there is no reason to believe scenarios that have the largest party increasing in size (and being almost always the Liberals), and correspondingly the effective number of parties falling. With 338 or so districts, likely there would remain room for several parties, and periodic minority governments (and alternations between leading parties), just as the SPM predicts for a country with that assembly size and single-seat districts.

As I have noted before, it is the UK that is the surprising case. Its largest party tends to be far too large for that huge assembly (currently 650 seats), and its effective number of seat-winning parties is “too low”. Maybe it needs AV to realize its full potential, given that the simulations there showed the third party benefitting (at least when it was larger than it’s been in the two most recent elections).

Bottom line: I do not buy the “FPTP on steroids” characterization of AV. I can understand were it comes from, given the presence in Canada of a large centrist party. I just do not believe Liberal dominance would become entrenched. The large assembly and the diversity of the country’s politics (including its federal structure) both work against that.

I agree with electoral reformers that PR would be better for Canada than AV. I also happen to think it would be better for the Liberals! But would AV be worse than FPTP? Likely, it would not be as different as the “steroids” claim implies.

Spill time?

So, who is the PM of Australia at the moment? It’s getting interesting. Again.

Second and third questions: What is the origin of the term, spill, to refer to an intra-party leadership challenge? Is Australia the only country where this term is used?

And for some comparative data context, see this planting from 2010.

There also has been an ongoing conversation about the current case at a planting from 2015. This topic of spills really overflows down under.

Malaysia election 2018

Malaysia’s election counting is underway, and reports abound that the opposition alliance has won. (Opposition, but led by an aging former prime minister who defected from the long-ruling party.)

Malaysia uses plurality in single-seat districts (FPTP), and is (in)famous for its severe malapportionment. It will be interesting to see how big the vote swing is, but the seats outcome apparently will be close. The BBC report linked above says the opposition has 115 seats out of 222.

President of South Korea announces constitutional reform proposal

South Korean President Moon Jae-in has announced his support for amending the South Korean Constitution to allow presidents to serve two four-year terms, instead of the current non-renewable five-year term. Moon, of course, came to office following the impeachment of Park Geun-hye, who became embroiled in a corruption scandal at the end of her non-renewable term: a similar fate befell her predecessor, Lee Myung-bak, who was recently arrested for a wide range of corruption charges.

Presumably, the idea behind this proposal is that it will encourage presidents to improve their behaviour at the end of their terms, given that they will be entitled to seek re-election. The proposal would also mean that members of the National Assembly would serve terms of the same lengths as the President, although elections to the two offices would not become concurrent–indeed, given that Moon’s term expires in 2022, and that the National Assembly’s term expires in 2020, it would shift South Korea to having legislative elections consistently in the middle of presidential terms.

The proposal has a number of other features. The Prime Minister will no longer be expected to act “under order of the President”, the voting age will be lowered from 19 to 18, and the President is no longer able to appoint the head of the Constitutional Court. However, there would appear to be no change in how the Prime Minister is appointed or removed: the Assembly can only pass a motion recommending that the PM or a minister may be removed, which both Samuels and Shugart (2010) and Robert Elgie have interpreted as not being sufficient for semi-presidentialism. The Prime Minister will also remain nominated only by the President (subject to Assembly confirmation).

Passage of the amendments requires approval of two-thirds of the National Assembly and majority support at a referendum with a majority turnout threshold. Moon’s Democratic Party only holds 121 seats in the 300-member assembly, and the opposition right-wing Liberty Korea Party holds 116, giving that party veto power over any potential amendment. That party appears to oppose the amendment proposal, instead apparently supporting a switch to semi-presidentialism, although the Democratic Party could block that. Moon’s proposal has greater public support, although the vast majority of the electorate support at least some change.
